A close button that finishes all activities

Question

I have 5 activities in my android app,on last activity i want a close button that exits the app by finishing every activity one by one?

Answer 1

You can do the next steps:

In the activity where you want to exit do the this:

Intent intent = new Intent(this, RootActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//this will clear all the stack
intent.putExtra("extra_exit", true);
startActivity(intent);
finish();

and in RootActivity.class's onCreate and onNewIntent:

public void onCreate(Bundle savedInstance){
    ...
    if(!checkExtraToExit(intent)){
        //do activity initialization
        ...
    }
    ...
}

public void onNewIntent(Intent intent){
    if(!checkExtraToExit(intent)){
        super.onNewIntent(intent);
    }
} 

public boolean checkExtraToExit(Intent intent){
    if( intent.getBooleanExtra("extra_exit", false)){
        finish();
        return true;
    }
    return false;
}
